 I'm ready to torque down the heads on my SBC and just realized that the book 
I'm using might not have the correct info I need.  It says 60-70 lbs, with a 
footnote for BB motors with four bolt mains that on those, the the outers get 
65 lbs and the inners get 115 lbs.  My book is a 1972 issue, so I'm not even 
sure they had four bolt small blocks then, which is what I have. I did notice 
that after only two runs last fall, when I pulled the heads there was a spot on 
the head gasket that was already getting a little discolored. Of course, that 
could have been a warped head, which, if it was, Tom has fixed for me. Do four 
bolt small blocks get different head bolt torquing? Do "built" motors get more 
torque than stockers?
Here's what I got:   SBC, block originally from 1982 1 ton truck, four bolt 
mains, Stock crank, flat top cast pistons, Sarda re-worked 882 heads, Crane cam 
with solid lifters, roller rockers, crane rocker stud girdle.  I redline it at 
6250 RPM (but might get crazy and try 6500 once this year).  What should I use 
for head bolt torque specs?

PS. Don't go trying to report me to the American Medical Association.  My 
doctor would die if he thought I was going to try and torque down a set of 
heads.  My next door neighbor is going to do the acutal wrench pulling for me.
